What organs make up the human renal system?

The human renal system, also known as the urinary system, is composed of the following organs:

• Kidneys: A pair of organs responsible for filtering the blood to remove waste products and excess substances, regulating electrolyte composition, and producing urine.1
• Ureters: Two thin, muscular tubes that transport urine from the kidneys to the bladder.1
• Bladder: A sac that stores urine until it is ready to be voided.1
• Urethra: The tube through which urine is eliminated from the body.1

Within the kidneys, the functional units responsible for urine production are called nephrons. Maintaining the health of these organs is essential, as the progressive destruction of nephrons or other renal damage can lead to serious conditions such as chronic renal failure.23
